anybody who has done this before or understands how to do this, I was
wondering if you know how to "tell" the kernel how
much memory there is in the system. An example would be if I have 512MB
of RAM, but only want the system to know that there is about 500MB in
RAM, so that 12MB does not exist to the OS/kernel. Would this require
mucking about in U-boot? or can I just define this in the kernel
source? Thanks

Most bootloaders including u-boot pass a board information
structure that includes a variety of information including the memory
size.
Also I think top of memory is also typically passed to the Linux
Kernel as a register parameter by the boot loader.
